It was the first of the centre's planned Soundscape performances and also involved fellow Dunedin singers Kerensa and Dell.
Ecosanctuary marketing manager Kerry Buchan said about 40 people enjoyed the event from 1pm to 3.30pm.
''We would like to have a series of Soundscapes and grow them to be an irregular, regular thing.
''Saturday was absolutely glorious, the sun was shining and everyone was singing along - it was just beautiful,'' Miss Buchan said.
A Soundscape concert involving traditional Maori musician Richard Nunns was planned for June, and there might be another held before then, she said.
Ecosanctuary administrator Tania Turei said it was hoped the centre could host performances every month or two.
''It's such a great venue, to be able to look out at the landscape.
''Saturday's performances were diverse but all really natural, and we've got so much talent in Dunedin,'' she said.
Admission to Sanctuary Sirens was free, but some Soundscape performances would include a charge.
